Overview

This HTS category, 2933.49.17.00, specifically covers "Ethyl ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylate." This compound is characterized by a quinoline ring system that is hydrogenated at the 1 and 4 positions, features a ketone group at position 4, a trifluoromethyl substitution at positions 6, 7, and 8, and an ethyl carboxylate group attached at position 3. Its classification within this broader group of quinoline and isoquinoline derivatives signifies its complex heterocyclic structure.

Within the "Other" subcategory of quinoline derivatives (2933.49), this specific entry is distinguished from its siblings by its precise chemical structure, particularly the trifluoromethyl substitutions and the ethyl ethylcarboxylate moiety. For instance, 4,7-Dichloroquinoline is defined by its chlorine substituents, while Ethoxyquin is an ethoxy derivative. Similarly, 8-Methylquinoline and Isoquinoline represent simpler substituted quinoline and isoquinoline bases. The presence of the trifluoromethyl groups and the specific ester functionality in ethyl ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylate uniquely identifies it for classification purposes.

As this is a leaf node within the HTS, there are no further subdivisions or subcategories under 2933.49.17.00. This means that any compound precisely matching the description of ethyl ethyl-6,7,8-trifluoro-1,4-dihydro-4-oxo-3-quinolinecarboxylate will be classified here. The classification relies on the definitive chemical name and structure, with no alternative isomers or closely related derivatives falling into this specific sub-heading.
